This should go without saying, but you could drop the rotisserie of creepy personas you're trying out and just hang. I understand that you can't fix yourself in a day, but any non-creepy effort would be met with positive reinforcement, and you'd be able to condition yourself to relax and just be a human being, at least most of the time. Everybody has their issues that flare up now and then (just ask
@LogicalInsanity), but your mental problems don't have to define you all of the time. You should think it over, and maybe consider some chemical help. Somebody fucked you up bad and it wasn't your fault.
